A compact all fiber refractive index sensor based on modal interference

In this paper, we propose and experimentally demonstrate a compact all fiber refractometer based on fiber modal interference. Different from other published program mostly based on the interference between high order modes in the Multi-mode fiber (MMF), we use the interference between core and cladd...
